Question:
How to Print alternate elements of an array?

Summary:

Suppose we have an array or a word with “N” number of the alphabet. We have to use Java code to print all the alternative numbers or digits available in that alphabet.


Solution:

Here is the code:

//User function Template for Java


// arr[] is the array 

// n is the number of elements in array.

class GfG

{

    public static void print(int arr[], int n)

    {

        for(int i=0;i<n;i++){

            if(i%2==0){

                System.out.print(arr[i]+" ");

            }

        }

    }

}


Explanation:

  1. Function Definition: The code defines a class named GfG with a static method print, which takes two parameters: an array of integers arr[] and an integer n representing the number of elements in the array.


  1. Iteration Over Array: Within the print method, a for loop is used to iterate through the array elements. It starts from index 0 and continues until i is less than n.


  1. Conditional Printing: Inside the loop, an if statement checks if the current index i is even using the condition i % 2 == 0. If i is even, the element at index i of the array arr[] is printed using System.out.print(arr[i] + " ").


  1. Method Conclusion: The method ends after closing the if statement and the for loop. This code effectively prints every element at an even index of the input array, separated by spaces.
